DRAFT-TUBE FOR EFFERVESCING DRINKS.

SPECIFICATION forming part of Letters Patent No. 358,650, dated March 1,1887.

Application filed October 1-1, 1886.

To aZZ whom it may concern:

Be it known that I, WILLIAM I. CLARK, of Medford, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Draft-Tubes for Effervescing Drinks and other Liquids,which will, in connection with the accompanying drawings, be hereinafterfully described, and specifically defined in the appended claims.

Fig. 2 is a top plan view of theholder of the valve and packing, the valve, its case, and thevalve-carrier being shown in place therein. Fig. 3 is an inverted planview of the gland. Fig. 4 is an inverted plan view of the valveactuatingkey.

My invention relates to draft-tubes of apparatus from which variousefferveseing and other drinks are drawn; and it consists in features ofnovelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the body of the draft-tube,whichis supported upon the conduit tube or arm B, extending from Arectangular bar or holder, 0, termed the valve and packingholder, isseated in an open slot extending through body A. In the upper portion ofbody A is screwihreaded the gland D, provided with a series of radialarms by which to actuate it. A valve-actuating key, E, having a lever,F, is arranged axially in said gland. To the bottom of body A is securedthe funnel-shaped nozzle G. In a central passage through holder 0 isseated the valve-case H, which is interlocked in holder 0 by alongitudinal rib, a, which is seated in a corresponding side recess orslot in the holder, as shown in Figs. 1, 2.

In the bottom of the opening of holder 0 is seated the disk-like packingI, which is interlocked by its projection to in the same manner as isvalve-case H. Upon packing I, and within case H, is seated the valve J,while directly above it is the valve-carrier K, whose fins b, seated inholes 0 in the valve, cause the latter to rotate with the carrier, saidcarrier and valve being perfect disks to rotate in case H, and havingeach acentral passage to receive the sleeve g of said case. In the topof said case is formed the arc-like or semicircular slot (1, whichextends entirely through the top, as shown in Figs. 1, 2, while throughvalvecarrier K is formed a shorter but similar slot, 0. Upon the lowerend of key E is an axial pin, f, which fits in the central passageincase H, and there is also formed on said key, at one side of said pin,an arc-like stud, h, which passes through curved'slot cl in case H andenters slot 0 in carrier K, as shown in Fig. 1, filling said slot; andby actuating the key by its lever F the carrier and valve may bereciprocated in a rotary path to the extent per mitted by the longerslot (1 in the case.

The disk I, of leather or other suitable material, seated between thelower internal face of the slot through body A and the valve J, servesto pack the face of the valve, while the circumferential wall '5 of caseH, which is by the action of gland D forced against disk I,

serves to form a liquid-tight joint around the valve, and the similarcontact of sleeve 9 forms a like joint around pin f of key E. Aconcentric rim or lip, 7c, in the top of case H is seated upon thering-packingj in carrier K, and a concentric lip, on, upon the lowerface of gland D is seated upon the ring-packing Z, inserted in saidcase, as shown in Fig. 1, the packing-ring j serving to prevent wear andfriction when the valve is actuated by the key, and packing Z performingthe same office when the gland is rotated to seat the valve upon itspacking-disk with due force and pressure.

In Fig. 14 is shown a passage, n, in holder 7 G, which communicates withpassage through the vertical wall of case H, which connects with acircular recess, q, therein, said passages serving to indicate by thedripping from passage n, in case of defective packing, that such defectexists.

Having thus described the construction of the body of the tube, thevalve, and coacting parts, I will next describe the conduits or passageswhich are opened and closed by means of the valve and by which the fluidis delivered into the drinking-vessels. The inlet-passage s in body Acommunicates with a small chamber, 14,. at the inner end of supply-pipeB, and

,with the inlet-passage w in packing I, asshown in Fig. 1. In saidpacking are also formed two outlet-holes, (marked it and 22,respectively,) which respectively communicate with passagescorrespondingly marked and formed in body A below said packing, saidpassage t being the outlet for the large or spraying stream, and passage1; for the small or sharp stream, as it is termed, (the connection ofsaid passages to with the delivery-nozzles being hereinafter stated.)

In the lower side of valve Jare two holes, y 2, connected by passage 00,formed in the body of the valve, said holes being so positioned thatwhen lever F of key E is moved to its extreme limit in one directionhole y will be coincident with inlet-passage w in packing I, and hole awill be coincident with hole a in said packing, and the fluid enteringthe valve through hole 3 will pass out through hole 2 in the valve, andthrough the hole a in the packing and in body A, and will be deliveredas the sharp stream; but when lever F is moved to its opposite limithole a is coincident with inlet to and hole 1 is coincident with hole 16in the packing and in body A, and the liquid ontering the valve throughhole a will be delivered through passage t as the large or sprayingstream. The liquid which enters passage t from the valve, as described,descends the same, as shown, and is delivered inside nozzle G throughcross-passages 2 in the flattened neck-like portion 3, as is shown inFigs. 1, 6, and theliquid that enters passage 22 descends the same, asshown, and enters the small chamber 4 in portion 8, whence it passes bycross-passages 5into axial passage Gin nozzle 7, whence it is deliveredas the sharp stream; but

said delivery devices shown below said pas sages t and o are not hereinclaimed as new, as they, in part at least, constitute features of aformer invention secured to me by United States Patent No. 138,615,issued May 6, 1873; and I do not herein broadly claim a holder, 0, whichis insertible and removable from the outside of body A, as the same ispatented to me in United States Patents Nos. 222,869, 248,918, and257,472, and respectively dated December 23, 1879, November 1, 1881, and

May 9, 1882.

What I claim as my invention is 1. The combination, with a draft-tube,of removable holder 0 and a valve seated within the holder andconstructed and ar- 3. The combination of a valve adapted to v berotated, a disk-like carrier removably interlocked with said valve toinsure coincident movement thereof, and a rotating key interlocked withsaid carrier, whereby the valve is rotated by the key through its actionupon the carrier, substantially as specified.

4. The combination of holder 0, the valvecase interlocked therein,thevalve iuclosed in said case, and the valve-actuating key, allsubstantially as specified.

5. The combiuation,with the packing-disk, of the valve and thevalve-case with its internal sleeve, and an actuating-rod formed tointerlock with the valve-case, substantially as specified.

6. The combination, with body A, having inlet-passages andoutlet-passages t and 'v, of packing I, having passages coincident withsaid passages in the body, and valve J, having holes y z, united bypassage as and positioned to respectively serve as either the inlet oroutlet passage, according as the valve is actuated, substantially asspecified.

7. The combination, with the valve-carrier, the valve-case, and thegland, of yielding ring j, the concentric lip 7c, ring Z, andconcentriclip m, respectively formed, combined, andarrangedsubstantially as specified.

8. The combinatiou,with holder 0, the valve and valve-case thereinarranged and duly packed, of tell-tale passage p in said shell, and thecoincident passage a in said holder, arranged to indicate the leakageresulting from imperfect packing, substantially as speci fied.
